Elektrische wijn vacuümpomp

Hello,
After having used a manual wine server for many years, I'm somewhat puzzled by your product. When pumping manually , it used to take maybe 30 to 40 seconds before one couldn't pull the device and you could hear very distinctly and loud the air getting in again when removing the cork.
With your product, the machine pumps for maybe 10 seconds only, and when you open the cork again, you hardly hear anything...
Could you please explain the functioning of your product a bit more that in the instructions booklet, like, how many seconds pumping for 3/4 of a bottle, for half a bottle, for 1 quarter of a bottle....
Any other detail would be most welcome
Best regards
Isabelle Scherrer

Prima ding. Had ik eerder moeten hebben. De vormgeving is helaas niet erg opwindend. Dat kan beter!!

The vacuum is not as good as with the Vacu Vin hand pump. After the electric pump automatically shuts off, it takes yet two or three actions more of the manual pump to hear the "click", indicating that the vacuum is complete.

Fonctionnement parfait et simplicité utilisation

From my experience, it's a huge difference in taste if there's oxygen in the bottle or not. I had two different systems before. None of them worked properly. They did their job but were not robust so that both became defect after a few months. In addition, I only could use them for one single bottle.
Using this Saver is a huge difference. At the beginning I thought that it did not work because it was very easy in handling, too easy from my first impression. The connection between the electric part and the closing part is so loose that I could not really imagine that it will work. But don't worry-it works very well.
I am really happy and recommend this part.
